ed new and useful Improvements in Speed vand Time Recorders, of whichthe following is a specification.

My invention relates Vto mechanism for recording the movements'ofdevices such afs automobiles and other vehicles, rotating shafting ofall kinds, the speed of marineV and stationary engines, of steamlocomotives and electrically propelled cars, and all similar devices,and has for its objectto provide certain improvements in the same aswill be hereinafter more particularly described and claimed, referencebeing had to the accompanying drawings, in which: 1

of the mechanism being shown detached and elevated. Figs. S, 9, 1() and11 are detail views of various parts of the mechanism. Fig. 12illustrates a section of a recordingsurface showing the marking of theperforating needle thereon.

Similar numerals 'of reference denote corresponding parts in the severalviews.

In the said' drawings the reference `numerall denotes the casing of theapparatus, the same being provided with suitable cover, not shown,hinged thereto at 2, and adapted.- to .be retained and locked in itsclosed position, preferably water-tight, by a suitable lock 3.

Permanently bolted to the underside of the casing 1 is a casing-plate 4,inclosing and forming a water-tight bearing for the shaft 5, which isformed into a worm shaft (l at its inner end, engaging and operating aworm wheel 7, and preferably screw-thread.

ed at its outer end to receive the couplingl S of a flexible shaft 9that is rotated from the moving part of the device to be recorded, such,for instance, as the hub of a vehicle, in any suitable manner. Theworm-wheel 7 vis mounted to freely rotate on a spindle 10,

and is formed with a hub 11 extending .through the base of the casing 1and carries a cam-wheel 12 at its inner end. The inner end of saidspindle- 1f? is screwed into a base-plate 13 xed in the casing 1 abovethe cam wheel 12.

Mounted on the base plate 13 is the motive power of the apparatus, forwhich I prefer to employ a clock-train 14: with the escapementmechanismremoved, said clock train being preferably an eight-daymechanism. Connected to the minute hand staff 15, in a mannerhereinafter described, is a gear wheel 16 meshing in turn with asimilar'gear wheel 17 mounted on a stud 18 carried by a cross plate 19fixed to longitudinal guide bars 20, that are in turnfmounted on acarrying plate 21 forming part of the framework ofthe mechanism. On theside of gear wheel 17 opposite to the driving gear wheel 1G is mountedon the base plate 13 another clock train 22, the same being alsopreferably of the eight-day variety, and being provided with the usualescape` ment mechanism 22. vFixed to the minute hand stati' of saidclock train 22 is a gear wheel 2-1 similar to gear wheel 1G, and alsomeshing with gear wheel 17, said clock train thus serving, through itsescapement mechanism, to synchronize the movement imparted to gear wheel17 from driving gear wheel 1G. The spring of clock train 11 thus exertsits tension freely on gear wheel 17, but said gear wheel is controlledaccurately in its movement by clock train 22 to rot-ate. once an hour.'The upper surface of gear wheel 2l may be marked with the minutes, asshown in Fig. 1, to indicate the position of the mechanisn'i.

.Mounted on the stud 1S of gear wheel 17, and beneath the cross plate1t), is a small pinion gear wheel 25, that in turn meshes with an oblongrectangular internal rack formed in a rack plate (3 laterally movable incross guide bars 27, and longitudinally movable, together with saidcross bars 27, in the guide bars 2O mounted on carrying plate 21, saidsmall gear wheel 25 being of a (,liameter too small to engage theopposite longittuiinal rack teeth of rack plate at the same time, seenin Fig. 3, and

l said diameter of said gear wheel 25 being,

vto

Y with the transverse teeth at the ends of the oblong rectangular rackwill shift said rack plate laterally in cross guide bars 27, the

pin 30 at the same time registering with one or the other of openings 29to permit said lateral movement, and said gear wheel 25 will be thusalternately placed in mesh with the opposite longitudinal rack teeth ofrack plate 26, and wlill thus reciprocate rack plate 26 in its guidebars 20, the pin 30 maintaining said rack plate in fixed krelationtransversely, by its engagement `either in slot 28 or against the outeredge of rack plate 26, until the shift transversely at each end of itsmovement occurs.

Mounted to` move freely vertically in a .bar 31 iXed to and reeiprocatedwith rack plate 26, is a puncturing marker 32, to be more particularlyhereinafter described.

As best seen in detail in Figs. 6 and 11, there is pivoted at 33 in twovertical standards 34, rising from the base plate 13, a bent levercomprising an upper longitudinal arm 35, a vertical portion 36, and alower horizontal arm 37. Said lever is normally I. forced inward towardstandards 34, below its .pivot 33, by a strong spring 38, and has itslower horizontal arm 37 in constant contact with the cammed periphery 39of Cain-plate 12, as shown in Fig. 6. The inner end of the upperhorizontal arm 35 is guided vertically in a slot 40 formedl in astandard 41 mounted on base plateV 13, and pivoted to said arm 35intermediate its length at 42, is an arm 43, whose inner end also liesin slot 40 of standard 41,` andvwhich is recessed at one side to receivesaid arm 35, as best seen in Figs. 6, 7 and .11. Said arms 35 and 43 liein the path of travel of marker 32, which, as shown in'F ig. 7, restshalf on each of them, and thus receives the impact of each of them whenarm 37 is suddenly released by passing-one of thecams 39 of camplate 12.Said arms thus form a com;

` pound lever that, as best shown in Fig. 11,

will impart to the marker 32 approximately the same stroke or blow nomatter what its position may be longitudinally withrespect to said arms.

In order that the marker 32 may impart normally a series of lightpunctures or blows, and at predetermined intervals a deeper puncture, Iprovide the following roede/ie mechanism: As best seen in Figs. 5 and 7,l'mount in the underside of a top plate 44 a transversely sliding stopplate 45 having a guiding tongue 46, said stop plate when in thelposition shown in Fig. 5 having its inner edge 47 overlying one edge ofthe shoulder 48 formed on the body of the marker 32, so that with plate45 in this position the blows imparted to said marker 32 will becheckedby the contact of shoulder 48 thereon with said plate 45. Saidplate 45is apertured at 49 to receive a pin 50 mounted on an' arm 51pivoted on a vertical rock shaft 52 extending through base plate 13 andfixed to acam 53 on theI underside of said plate 13, shown in dottedlines in Fig.l 3, said cam being pressed in one direction by a spring 54and having its free end lying in the path of travel of a pin 55 fixed tothe upper side of cam wheel 12. Said cam wheel 12 is preferably so'geared with the vehicle wheel hub as to be rotated once for every miletraveled, and said pin 55 will therefore contact with said cam 53 oncefor every mile traveled. Said contact will shiftsaid cam, and throughrock shaft 52, arm 51 and pin 50, will shift stop plate 45 to theposition shown in Fig. 7 out of the path of vertical movement ofshoulder 48 on marker32, and will maintain the parts in said shiftedposition during the passage of one of the cam teeth 39 on cam-Wheel 12past the arm 37 of the bent lever, whereby one puncturing impulse orblow will be given to the marker 32 with .the -parts in said position.This impulse or blow being unchecked by thev stop plate 45 willnecessarily be a much deeper puncture in the recording tape, hereinafterdescribed, and will thus register the travel of a mile. The 'passage ofpin 55, past cam 53 will release the latter, and the same, together withstop plate 45, 'will be returned to its normal position by spring 54.

Mounted in suitable brackets 56 rising j from the base plate 13 isarecord tape delivering drum 57, against 'the tape 58 mount ed thereoninipinges fa spring 59 to control the delivery of the tape therefrom,the only peculiarly novel feature of construction of j said drum beingAa slot 6() arranged in and passing completely through the wall of itsbody to receive and' retain the end ofthe tape, said slot being disposedat an angle to the diameter of said drum, in order to more 1 easilyreceive and more securely retain the tape end, as vbest seen in'Fig. '7.On the other side of the marker `32is mounted, in brackets 61, asimilarly slotted receiving drum 62, a pair of pivoted retaining jaws 1v63 servingto removably retain the axis of said drum in position. Thesaid tape is placed upon the drum 57 with its surface unmarked, butduring its passage between the small rollers 64 and 65 freely mounted 1at its i in the top frame of the apparatus, and because of the factthatl the roller. 64E is provided on its periphei'y with a series ofscoring ribs GG, best seen in Fig. 1, that register with similar groovesin the roller 65, said tape 58 becomes scored loiigitudinally to marksay tive minute divisions of timetransversely on said tape. In orderthat the pressure of roller (i4- may be adjusted I mount its bearings inthe free edge of a flat spring plate GT secured atGS to the top frameand provide therein an adjusting screw 68 tapped into said top frame.

The mechanism for feeding the tape 58 is best seen in Figs. 3, 11 and(l, and consists of a horizontal pin (39 lixed to the. vertical portion3G of the cam lever below its pivot 33, said pin G9 connecting, by meansof a link 70, with an actuating pawl T1 pivoted at Q tothe base plate13, and having a knife edge T3 near its Vfree end lying in the path ofen-V gagement with a ratchet wheel 71, that is in turn mounted on oneend of a shaft 75 rotatable in a bearing 76 supported from one of thestandards 3i, said shaft T being formed r end into a worm shaft 77 inengagement vit-li a worin .whe-el 78 mounted on one end of the shaft 'T9of drum (l2, a springpressed stop-pawl 80 also engaging said ratchetwheel 7l. lVith this Amechanism it will be obvious that each impulseimparted to the lower horizontal arm 37 of the bent lever by the camwheel 12 will rotate ratchet wheel 'Td one tooth, and will tlierebysimilarlv rotate drum 52 and as I have Jrovided 'plate being curved.outward to-reach said lever 95, as seenI in Fig. 1, and carrying camwheel 12 with twenty-four cam teeth 39, the tape 58 will be fedintermittently once for every twenty fourth of a mile traveled by thevehicle.

The mechanisinfor printing the hours on the tape is as follows: Aprinting wheel 81 is mounted on a spindle 82 on the underside of the topplate 83, said wheel being provided on its underside near its peripherywith type indicating the twenty-four hours of a day, the p. in. hoursbeing preferably distinguished from the a. m. hours by'dots placed afterthe same, as best seen in Fig. 5, and said wheel overlying at one'edgethe margin of the t-ape Fixed to the spindle 82 on the upper side. oftop plate 83 is a toothed wheel 81, by which the printing wheel 81 isrotated. The movementof this toothed wheel is controlled by a springlessiawl 85, pivoted at 86 and having one end engaging the teeth of wheel81v and its other end in contact with the 'periphery of a cam wheel 87`mo-unted on the starl' 18' of gear wheel 17, -as best seen in Fig. 1,and being provided with a cam recess 88 and projecting pin 89 in itsperiphery, the two being so positioned relatively that theA recess 88will register with the end of pawl 85 just as pin 89 engages one of theteeth of wheel 84. New as the cam wheel 87 is rotated with wheel 17 oncean hour, it follows that once an hour pin 89 thereon will engage withand rotate wheel 8% and printing wheel 81 the space of one tooth ofwheel 84, and as the latter has `twenty-four teeth,corresponding withthe type on wheelp81, said type will be successively presented toV theprinting point hereinafter described. The operation of the pawl 85 willbe obvious, the same by dropping in recess 88, as the pin 89 contactswith a tooth of wheel 84, releasing the tooth engaged Vby its other endto permit the rotation of wheel 8-1. and as it rides out of recess 88'being again forced into holding engagement with the teeth of wheel-84.

Pivoted at 90 to one of the standards 34 of the frame is a lever 9.1,the same extending inward parallel with the compound lever 35, 43, andhaving fixed at its inner end a transverse bai` 92 passing beneath thetype gear surface of printing wheel 8l, and forming a1 printing hammer,as best seen in 1 and 3. Also tixedi'tosaid lever 91, and passingtransversely over the compound lever 35, 13, is an actuatingbar 93adapted to receive impulses from said compound lever,

on its upper ,surface a lug 99 adapted to engage the teeth of wheel 811.The other end of this sliding plate has a projecting end 100 adapted toContact with one end of a lever 101 pivoted intermediate its lengt-h ontop plate 83 and contacting at its other end with a vertical aim 102fixed to the lever 91. Normally the sliding plate 98 ispuslled inward,and the upper end of bell crank lever 95 contacts against the side ofsaid plate, ythurs keeping its upper end away from wheel 84 and raisingits lower end, which in turn raises rod 94 and vactuating bar 93, thelatter being thus out of the limit of movement 'of compound lever 35,43, and receiving no impulse when the latter is actuated. But whenthe'printing wheel 81 and toothed wheel 84 rare actuated a step' throughpin 89 on cam wheel 87, which occurs once an hour, one of the teeth ofwheel 84 contacts with thelug 99 on slidingplate 98, thus forcing thelatter outward and releasing the upper arm of bell 'crank lever 95,which permitsI the parts to assumeA the position shown in Figs. 1 and Gwherein the actuating bar 93 is in contact with the compound lever 35,43 in position to receive an impulse therefrom result of this nextimpulseV imparted to the compound lever is that through the rigidconnection between actuating arm 93, lever 91 and printing hammer 92 thelatter forces the overlyingptape against that type on wheel 81 thathappens to be at the printing point, thereby imparting the impressionthereof to the tape. At the same time the upper end of arm 102 fixed tolever 91 is forced outward, thereby rocking lever 101 on its pivot,which forces in the sliding plate 98, and as the upper end of bell crankrlever 95 has been simultaneously moved out-ward away from the path oftravel of said sliding plate, the latter will resume its initialposition yready for a fresh impulse from the teeth of wheel 84. It willthus -be seen that once an hour the tape is printed withv said hour, butonly if the vehicle is in motion. l

In order that the gear wheel 16 may be temporarily disconnectedfrom thesta 15 of the driving clock train 14, for the purpose of setting to thecorrect time, I provide the following mechanism, shown in detail inFigs. 8 and 9: Said gear Wheel 16 is mounted to rotate freely on staff15, and has fixed to its underside a ratchet wheel 103, with which isadapted to engage a pawl 104 pivoted on a shaft 105 carried by a pawldisk 106 that is fixed to staff 15.

vAlso fixed t'o staff. 105, on the underside of disk 106 is a hookedpawl 107, that is adapted to engage a ratchet wheel 108 that is fixed tothe top plate of theI driving clock train 14n `Said.' pawls 104 and 107are so adjusted that while one of them is completely engaged with itsratchet wheel the other will be disengaged from its ratchet wheel,though, at the same time, they cannot both be disengaged at once. 7Withthe parts in the position shown in Fig. 8, the pawl 104 is in engagementwith its ratchet Awheel 103 and the' pawl 107 disengaged,

the power of the driving train 14 being thus applied to the gear wheel16. Now, when it is desired to disconnect gear wheel 16, the pawl disk106, which is a little greater in diameter than gear wheel 16, and hasits edge milled, is rotated manually against the tension of the drivingtrain 14 to'a slight degree, whichl results in pawl 104 being forcedoutwardly, and in pawl 107 being correspondingly forced4 inwardly toengage its ratchet wheelA 108. The driving train will thus be heldbyfpawl '107 against :running down, and the gear wheel 16 will be freeto be rotated. To restore the parts to their normal position it is onlynecessary to again move pawl disk 106 slightly against the tension ofthe Adriving train, when the operation will -be reversed and the pawl104 restored to its engaging position and the f. paw-l 107 disengaged,it being-apparent that as at no time are both pawls simultaneouslydisengaged, there will never'be any danger of the driving train beingreleasedto run down. In order to adjust the parts when the gear wheel 16is released, itis-necessary that gear wheel 24 on synchronizing clocktrain 22 be also released from its staff 23, and this'I prefer toaccomplish, as shown in detail in F ig. 10, by providing said staff 23with a. coned seat 109 against which the hub of gear wheel 24 contacts,a similar coned seat 110 being formed ont-he clamping nut 111, betweenvwhich conesx the gear wheel 24 maybe securely held to rotate with staff23, and yet may be readily loosened to rotate independently.

Briefly stated, the operation of the device is as follows: The part-sbeing first adjusted to correspond with the time of day or night, andthe pawl 104 into .engagement with ratchet wheel 103, the gear wheel 16is' placed under the tension of driving train 14 freely exerted thereon,which tension is communicated to gear wheels 17 and'24, the lat- I saidmarker 32 to cross the tape 58 trans-- versely once an hour. With thevehicle at rest, this movement, together witha feed of ltoothed wheel 84and printing wheel 81` one step an hour, as hereinbefore described, willconstitute the operation of the device; but with the lvehicle in motion,which is communicated to cam wheel 12 through flexible shaft 9, animpulse will be imparted `to the bentI lever formed of the parts 35, 36

and 37 once for every cam tooth 39 of cani wheel 12, and as said .camplate: is geared to rotate once for every mile traveled, said impulseswill be imparted everyI twenty fourth of a. mile traveled. Each of saidimpulses imparts a puncturing impulse to marker 32, and the blowimparted is,

through the operation of compound lever 35, 43, approximately the sameno matter what position said marker may occupy longitudinally withrespect to said compound lever. The penetration -of said marker 32lthrough the tape 58vis controlled to the same depth by the stop plate4:3 except once for every mile traveled, when, through the pin and theintermediate connections, hereinbefore described, said stop plate 45 istemporarily withdrawn from the path of the shoulder 48 on marker 32, andthe latter permitted to make a deeper, and, owing to its conical point,a larger puncture, thus ,recording on the tape the miles traveled. Thesaid tape while introduced into the device plain, is

scored longitudinally the rollers 64E and 65 to indicate tive minutedivisions of time,

, and once every hour, while the vehicle is in motion, said hour isimpressed on the in iier margin of the tape by the printing wheel S1 andprinting hammer 92, through the mechanism hereinbefore described. Itwill thus lbe seen that with a recording tape controlled in its feed bythe movement of the vehicle, a light puncture is made thereon once everytwenty fourth of a mile traveled, by a marker reciprocated across saidtape once an hour synchronously with the movement of a clock train; thatonce an hour said hour is impressed on said tape, provided the vehicleis moving; and that for eveijv mile traveled a larger puncture is madeby said marker in said tape.

' I have illustrated in Fig. 1Q a section of a tape showing a. record.This record shows that the vehicle started at 9.40 a. m. ruiming' :itabout vfour miles an hour until 10.05 a. m. when the speed increased toabout twelve miles an hour, until 10.35, when' the vehicle stopped afterrunning almost sii; miles, said miles being indicated by the deeperperforations. "Che vehicle started again at 12.45 p. m., running at therate of about ten miles airhotr, which speed Vwas increased at 1.10 p.ni. to about twelve miles an hour, which was kept up until 1.38 p. in.,when the vehicle again stopped. Running was again resumed at about 2.08p. m., the speed varying between four and six miles an hour until 3.10where the record ends.

lVhile I have described my invention as particularly applicable tovehicles for recording the running of the same, I wish it tobe'understood that I do not limit myself to such use, as the device may'be applied to any form of moving machinery, such as shafting, stationaryand marine engines, and the like. I also wish to be understood not tolimit myself to the exact details of construction shown and described,as the same may be varied in many particulars without departing from thespirit of my invention.-
